Single-mode cards are very expensive (the optics), for short distances
(several hundred meters) use multimode, the fiber is also much cheaper
then. And yes, you don't need any switches - I use them exactly this way.
As for the price... Frankly, I don't remember, the company paid for this
:-), I vaguely remember something like $700 per multimode 155Mbps card.
And the difference in pricing between single- and multi-mode card was
something like 3:1.
